Thanks Josh and good afternoon everyone and thank you for joining us on our first quarterly investor conference call. We plan to host similar corporate update calls to enhance transparency and highlight our progress, as we and our clinical partners advance our cancer vaccine candidates through multiple clinical trials. We'll also discuss our strategy for continuing to build shareholder value through successful clinical execution, as well as the upcoming milestone that we expect to achieve in the near and long-term. Joining me on the call today is Dr. John Bonfiglio, our President and Chief Operating Officer, who will provide further detail on our current and planned clinical programs. First, I'd like to provide a general overview of our Company for those who may be new to TapImmune and highlight some of our recent achievements. TapImmune is a clinical stage immune-oncology company that is distinguished by our focus on women's cancers. We are currently advancing two T-cell vaccine candidates in multiple phase 2 and phase 1/2a clinical trials. Our initial focus is on addressing the unmet need in women's cancers, specifically ovarian breast cancers, where reoccurrence rates are high following surgery and initial therapy. The time to reoccurrence is relatively short for these cancers, and survival prognosis is extremely poor once the cancer recurs. These cancers also tend to be resistant to most immunotherapies, which is why we believe we have a significant opportunity to improve the lives of these patients. Our novel immunotherapies are design to target both tumors and metastatic disease for intractable ovarian and breast cancer. Our T-cell cancer vaccine technology is engineered to overcome deficiencies of earlier approaches in this field. Our vaccines have the potential to be a powerful standalone therapy against a variety of cancers, as well as the central component of the leading combination immunotherapy, which is an exciting approach that many are undertaking in the clinic today. We are proud to be working in collaboration with industry and clinical leaders, including The Mayo Clinic, Memorial Sloan Kettering Cancer Center and AstraZeneca, all of which have thoroughly vetted our technology and recognized the value in advancing early candidates. This is based in large part on the data we've generated in Phase 1 clinical studies, which showed robust, sustained immune responses against our targets in over 90% of patients treated. We received orphan disease designation for the use of this vaccine in ovarian cancer and FDA fast track approval for one ovarian cancer indication. This further positions TapImmune to emerge as a leader in T-cell vaccine immunotherapy. I'd now like to tell you a little bit about our technology and how our vaccines are designed to elicit powerful and cancer immunity, as well as discuss what sets TapImmune apart from immunotherapy companies, based on our unique approach and market opportunity. Our technology is or has been derived from recent advances in cancer immunology and discovered, not in animals, but translational medicine, by observing what the immune system is responding to in cancer patients. As a result, our vaccines are comprised of a series of immunogenic peptides, derived from molecules that are over expressed on the surface of a majority of cancer cells we are targeting. Over expression of these molecules co-relates with disease reoccurrence and overall prognosis. We are looking to exploit the body's natural immunity to these relevant targets by identifying peptide and tissues that are being processed as part of a cancer patient's natural immune response. We then use those peptides as a basis for our vaccine. We use a carefully selected mix of both class1 and class 2 antigens, which is critical for stimulating both helper T-cells and tumor cells, to monitor robust T-cells response against the cancer sets. We expect this natural immune response to be effective against both the primary tumor as well as metastatic disease. We believe our vaccines will elicit a long-lasting memory, T-cell response against the cancer, and we are seeing some initial evidence of this in phase 1 studies. As I mentioned, we're focusing on treating women's cancers, because of a large and un-served patient population who are in great need of better treatment options. In the United States about 30,000 ovarian cancer patients, about 40,000 triple-negative breast cancer, and about -- and over 200,000 HER2/neu positive breast cancer patients are diagnosed each year. As the statistics are staggering about 1.6 million, there are about 1.6 million new cases worldwide of breast cancer and unfortunately about 500,000 women will die of this disease on an annual basis. Because our vaccines work differently, we feel we can provide benefit for women as a consolidation therapy to help prevent cancer recurrence, as well as second line therapy for women who are resistant to first line therapies. We're also doing some clinical work that combines our lead vaccine with an immune checkpoint inhibitor, to deliver the promise of immunotherapy to these patients who have few other treatment options. We are developing our vaccines as off-the-shelf products that are simple to manufacture and can be delivered by a simple injection. Selection of the molecular target and the antigens that make up the vaccine is key to ensuring that our vaccine will be effective for a majority of cancer patients in the disease we're targeting. The target for our lead vaccine candidate, TPIV 200 is Folate Receptor Alpha, which is over expressed in approximately 90% of ovarian cancer cells and more than 80% of triple-negative breast cancers. Folate Receptor overexpression is also correlated with the likelihood of cancerous recurrence. Yet importantly, some patients do develop spontaneous immunity against this natural molecule. That is the basis for our vaccine. TPIV 200 consists of five class II peptides, four within embedded class I T-cell epitope and one with an embedded antibody epitope. Importantly, humans vary genetically in their immune systems and TPIV 200 is expected to cover around 85% of human genotypes worldwide. This breadth of activity is supported by the results of our phase 1 studies. Our second lead vaccine is TPIV 110, which consists of five peptides targeting HER2/neu, which is overexpressed by approximately 30% of breast cancer patients. HER2/neu is also the target of a blockbuster monoclonal antibody therapy such as Herceptin or Parjeta, despite the fact that this approach is only effective for about 15% to 20% of HER2 positive patients, and can only be used for approximately a year. The unique mix of epitopes that combine TPIV 110 is expected to cover significant larger HER2/neu patient population than Herceptin, and remain effective for significantly longer. In addition, published data shows that the class I antigen in TPIV 110, that is one of the five antigens in the vaccine is the most effective class I antigen that we know in killing human breast cancer cells in culture. Based on these factors, we believe TPIV110 may be more efficacious for more women with this disease. Before I hand the call to John to go into further detail on our clinical programs, I'll quickly highlight some of our recent achievements. 2016 was an extraordinary year for our Company, setting us on a trajectory toward becoming a leading immune-oncology company and potential breakthrough for women with breast and ovarian cancer. As I mentioned, we successfully forged valuable relationships with important cancer centers and major pharmaceutical companies for collaboration in developing our vaccines. We also made important clinical progress with the initiation of multiple phase 2 clinical trials for TPIV200, including an immunotherapy combination with AstraZenica's checkpoint inhibitor, durvalumab in patients with platinum-resistant ovarian cancer, which is being conducted by Memorial Sloan Kettering Cancer Center. We also have Company-sponsored trials ongoing in Platinum sensitive ovarian cancer and triple negative breast cancer, as well as a planned Phase 2 study to be conducted by the Mayo Clinic and completely funded by a $13.3 million grant from the U.S. Department of Defense. In early 2016, the FDA granted us fast track designation for TPIV200 for treating platinum-sensitive ovarian cancer. As many of you may know, this important designation enables us to have frequent interaction with the FDA regarding the clinical development of TPIV200 for this indication and provides a pathway to accelerate the review of our new drug application once our clinical work is complete. We recently announced that we successfully completed a multi-ground production scale up as well as GMP manufacturing of the second clinical batch of TPIV200, which will be used to supply our ongoing Phase 2 study in Platinum-sensitive Ovarian cancer, as well as the upcoming Phase 2 study sponsored by Mayo Clinic for treating triple negative breast cancer. The successful release of our second lot of TPIV200s represented another important milestone for our lead vaccine candidate. As many of you may have seen, this morning we announced that our collaborators at Mayo Clinic received a second Department of Defense grant to fully fund a new Phase 2 study of our HER2/neu vaccine candidate in an early form of breast cancer. This then is the second clinical trial to be fully funded by a DoD grant, and we are excited for the study to begin later this year. We reached an important corporate milestone in early November last year when we successfully uplisted to the NASDAQ capital market. Listed on a national exchange expands our visibility and stock liquidity, and provides access to a broader investor base. When we were doing this, we also raised more than $9 million from the exercise of outstanding warrants and a small pipeline announcement [ph], and concurrently we removed, in excess of $26 million of derivative liability from our balance sheet. We are continuing to develop a stronger infrastructure and enhance capacity to [Indiscernible] institutional investors. It's all about clinical execution to drive greater shareholder value. I'll now hand the call over to John to provide greater detail on our clinical programs. John?
